The following error appears when attempting to compute or validate a model:"Pressure engine output set references a deleted selection set."Problem ID#: 56800
Under Analysis > Calculation Options, check the "Output Selection Set" field. If it's set to "<None>", choose the correct selection set or set this field to "All".
Current versions of the water products no longer has an option for "None." Based on that, upgrading will also likely resolve this issue. The steps to upgrade can be found at the following link: Download Haestad / Hydraulics and Hydrology software.
